背景不活动是导致慢性健康问题的主要因素。在这里，我们研究了基于计步器的身体活动干预（爱德华王子岛第一步计划，PEI-FSP）的活动和特定的健康指数在106久坐不动的工人。参与者从五个工作场所招募，其中大多数工作都是中度高度久坐。使用受试者作为自己的控制，身体活动（计步器确定每天的步骤）进行了比较之前和之后的12周的干预。评估体重指数（BMI）、腰围、静息心率和血压的变化。PEI-FSP由59%的参与者完成。每天的步数从基线时的7，029 +/-3，100（SD）增加到3.96 +/- 3.28周干预时的10，480 +/-3，224步/天的平台。参与者每天能够增加步数的数量与他们的基线BMI无关。平均而言，参与者的BMI，腰围和静息心率显着下降。腰围和心率的减少与每天步数的增加显著相关。相比之下，BMI的降低是通过每天的初始步数来预测的。PEI-FSP增加了久坐人群的体力活动。重要的是，那些在基线时BMI较高的参与者与BMI较低的参与者相比，其体力活动的增加相对相似。(C)2004年癌症预防研究所和爱思唯尔公司。All rights reserved.
Background. Inactivity is a leading contributor to chronic health problems. Here, we examined the effects of a pedometer-based physical activity intervention (Prince Edward Island-First Step Program, PEI-FSP) on activity and specific health indices in 106 sedentary workers.Methods. Participants were recruited from five workplaces where most jobs were moderately-highly sedentary. Using subjects as their own control, physical activity (pedometer-determined steps per day) was compared before and after a 12-week intervention. Changes in body mass index (BMI), waist girth, resting heart rate, and blood pressure were evaluated.Results. The PEI-FSP was completed by 59% of participants. Steps per day increased from 7,029 +/- 3,100 (SD) at baseline to a plateau of 10,480 +/- 3,224 steps/day by 3.96 +/- 3.28 weeks of the intervention. The amount that participants were able to increase their steps per day was not related to their baseline BMI. On average, participants experienced significant decreases in BMI, waist girth, and resting heart rate. Reductions in waist girth and heart rate were significantly related to the increase in steps per day. In contrast, reductions in BMI were predicted by the initial steps per day.Conclusions. The PEI-FSP increased physical activity in a sedentary population. Importantly, those with a higher BMI at baseline achieved relatively similar increases in their physical activity as participants with a lower BMI.
